creating fixtures for has_many :through

I'm stymied at how to create a fixture that establishes a has_many :through relationship.

I've watched the railscast at:   http://media.railscasts.com/videos/081_fixtures_in_rails_2.mov ... but that's for HABTM relationships. I've read:   2.0 Fixtures with has_many :through? - Rails - Ruby-Forum but that ultimately doesn't answer any question. So with no further ado:

==== The models: class User < ActiveRecord::Base   has_many :user_roles, :dependent => :destroy   has_many :roles, :through => :user_roles end class Role < ActiveRecord::Base   has_many :user_roles, :dependent => :destroy   has_many :users, :through => :user_roles end class UserRole < ActiveRecord::Base   belongs_to :role   belongs_to :user end ==== The schema:   create_table "users", :force => true do |t|     t.string "name", :default => "", :null => false     t.string "email", :default => "", :null => false   end   create_table "roles", :force => true do |t|     t.string "name"   end   create_table "user_roles", :force => true do |t|     t.integer "role_id"     t.integer "user_id"   end

The more I've looked into it, the more I think Marnen would be justified in telling me to put aside my Luddite tendencies: the fixtures framework creates an arbitrary (and brittle) separation between test data and test functions.

I'm currently grabbing the gems for RSpec and factory_girl.

So there!

Exactly! That's a big reason that fixtures suck. It's much nicer to use factories to create test data where you need it.

You may find Machinist easier to work with than FG. Also check out Faker, which is very useful with any fixture gem.

So there!

LOL! Well played. This is apparently my week to be snarked on the list. :stuck_out_tongue:

Best,
